I think I got it all figured out. Justin Bieber's New Year's resolution for 2013 was to never wear a shirt ever again.
The latest was Biebs caught shirtless at one of the most obvious shirtless environments: an airport.
He must be convinced the world can't go a day without seeing his amazing six-pack.
Below freezing weather in an airport in Poland, perfect for a stroll with a naked torso!
Keep it up Justin, we can't wait to see the next hot pics! Said no one ever.
